Pillow block and flange bearings are commonly used in construction machines and conveyor systems, therefore they are often exposed to dirt and dust. This exposure to foreign debris creates extreme loads that the bearings must endure. To withstand these harsh scenarios, metallic bearings must be regularly maintained and lubricated. With the new igus spherical balls made of the high-performance plastic iglide J, users can now rely on a self-lubricating and maintenance-free solution. The narrow igubal spherical balls are developed directly from the injection-molding process and can be inserted into existing metallic pillow block and flange bearing housings within seconds. Due to the absence of external lubricants, dirt and dust cannot adhere to the bearings, further minimizing wear. This can also mitigate machine downtime.
The long service life of the igubal spherical balls was demonstrated in a biomass chipper. Where metal bearings on the conveyor belt of the chipper had to be lubricated monthly, retrofitted flange bearings with the igubal spherical ball stayed wear-resistant for more than a year, without lubrication or maintenance, according to the company.
